Book excerpt: Excerpt from The Culture of the Central American Rubber Tree Progress in practical matters as well as in purely scientific subjects depends much upon theories. On the failure of the first experiments, the theory that rubber trees could be profitably cultivated was dis carded by many who came to the conclusion that planted trees will not produce rubber. This view is by no means extinct, especially among those who have abandoned rubber planting in disgust. An adverse Opinion of this kind is popular with some because it serves as a general explanation of failure and spares the annoying suggestion of cultural errors and oversights.

Book Synopsis Rubber Planting in Mexico and Central America by : Pehr Olsson-Seffer
Download or read book Rubber Planting in Mexico and Central America written by Pehr Olsson-Seffer and published by Forgotten Books. This book was released on 2015-06-25 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Rubber Planting in Mexico and Central America In 1805 an English translation of the paper was published anonymously, and now the name was changed to Castilloa. The translator (who is believed to have been Charles Koenig, the keeper of the mineralogical department of the British Museum) had no right to alter the name. A Mexican botanist had already, with just as little right, proposed to change the name to Castella, shortly after the plant had been described. Now we have in systematic botany certain recognized rules of nomenclature, and one of these is that of priority. As Castilla was the first name given, it should remain so. This question was discussed and settled in 1903 by O. F. Cook, in "The Culture of the Central American Rubber Tree" or Bulletin No. 49, Bureau of Plant Industry, United States Department of Agriculture, but it seems to have been overlooked. Different Forms of Castilla. Another question which is causing considerable misconception as regards our Central American rubber tree is that of species. Castilla elastica Cerv. in a very wide species, containing numerous forms. A species-making botanist could easily divide it into a dozen species or more. I have personally observed nine fairly distinct forms, but I still hesitate to recognize them as good varieties. Koschny, a Costa Rica planter, who has written considerably in "Der Tropenpflanzer" about Castilla in certain parts of Central America, speaks of several "species," but does not give satisfactory descriptions that would warrant his forms to receive the distinction of species. Cook described the form occurring on and near La Zacualpa rubber plantation in Soconusco, Mexico, as a new species, C. lactiflua. In Hawaii I saw a form planted from seeds obtained from a seed merchant in Paris under the name var. nicaraguensis. It certainly was different from any other form I have seen elsewhere. C. markhamiana is generally considered to be a separate species, and the Castilla grown in Ceylon is sometimes referred to as this species. Certain is that the Ceylon Castilla is not identical to any Mexican Castilla that has come under my notice. From the planter's point of view it is of little significance whether one or more species are cultivated so long as the rubber is obtained. But it is in this fact of the existence of many different forms in which we have to find an explanation of the reputed failure of Castilla in different places, where its success had been presupposed. If we plant seeds of the Castilla of the Atlantic side of Southern Mexico, with an almost continuous rainfall, on the Pacific slope of the Sierra Madre, where we have a distinct dry season of six months, the tree does not succeed in growth, the amount of latex is smaller, and a planter would soon find out that he had made a great mistake, had he tried this experiment on a large scale. It seems to me probable that if attention had been paid to this ircumstance, Castilla would be more of a favourite than it is.

Book Synopsis The Ceara Rubber Tree in Hawaii (Classic Reprint) by : Jared Gage Smith
Download or read book The Ceara Rubber Tree in Hawaii (Classic Reprint) written by Jared Gage Smith and published by Forgotten Books. This book was released on 2017-12-14 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Ceara Rubber Tree in Hawaii The latex, or milky sap, of the rubber tree is of very complex composition, containing starch, sugars, gums, resins, proteids, and salts, as well as rubber. The milk tubes are not continuous - that is, it is not possible by cutting through the network of tubes at the base of the tree to drain out all of the latex. The latex-bearing tissues may rather be compared to a series of short tubes joined end to end with permeable diaphragms between. In the living plant there is free transfer of latex from one tube to another, but there is no circulation comparable with the circulation of the blood in ani mals. There is no rise and fall of the sap, as is the common belief, and so far as has been determined, there is no ruling direction of movement at any time of the day or period during the growth of the plant. The circulation of the sap in the tree or of latex in the milk tubes is simply a process of life, a phenomenon of growth. The rubber in the latex in the milk tubes is supposed to exist as an emulsion, somewhat comparable to fat globules in milk. When a milk tube is ruptured, to permit its contents to escape, the rubber globules rapidly agglutinate, the function of rubber apparently being to close up wounds and prevent the loss of water from the tree by evaporation. The flow of latex when the milk tube is ruptured is not due to the continuity of the tubes, as would be supposed, but is because the latex is under tension in the growing trees. When the pressure is relieved by the breaking or cutting through of the tissues containing the latex, the tension being released, the milk tubes for a short radius around the wounds quickly empty themselves of their contents.

Book Synopsis Reconsidering Olmec Visual Culture by : Carolyn E. Tate
Download or read book Reconsidering Olmec Visual Culture written by Carolyn E. Tate and published by University of Texas Press. This book was released on 2012-01-18 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, scholars of Olmec visual culture have identified symbols for umbilical cords, bundles, and cave-wombs, as well as a significant number of women portrayed on monuments and as figurines. In this groundbreaking study, Carolyn Tate demonstrates that these subjects were part of a major emphasis on gestational imagery in Formative Period Mesoamerica. In Reconsidering Olmec Visual Culture, she identifies the presence of women, human embryos, and fetuses in monuments and portable objects dating from 1400 to 400 BC and originating throughout much of Mesoamerica. This highly original study sheds new light on the prominent roles that women and gestational beings played in Early Formative societies, revealing female shamanic practices, the generative concepts that motivated caching and bundling, and the expression of feminine knowledge in the 260-day cycle and related divinatory and ritual activities. Reconsidering Olmec Visual Culture is the first study that situates the unique hollow babies of Formative Mesoamerica within the context of prominent females and the prevalent imagery of gestation and birth. It is also the first major art historical study of La Venta and the first to identify Mesoamerica's earliest creation narrative. It provides a more nuanced understanding of how later societies, including Teotihuacan and West Mexico, as well as the Maya, either rejected certain Formative Period visual forms, rituals, social roles, and concepts or adopted and transformed them into the enduring themes of Mesoamerican symbol systems.

Download or read book Gulp: Adventures on the Alimentary Canal written by Mary Roach and published by W. W. Norton & Company. This book was released on 2013-04-01 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The irresistible, ever-curious, and always best-selling Mary Roach returns with a new adventure to the invisible realm we carry around inside. “America’s funniest science writer” (Washington Post) takes us down the hatch on an unforgettable tour. The alimentary canal is classic Mary Roach terrain: the questions explored in Gulp are as taboo, in their way, as the cadavers in Stiff and every bit as surreal as the universe of zero gravity explored in Packing for Mars. Why is crunchy food so appealing? Why is it so hard to find words for flavors and smells? Why doesn’t the stomach digest itself? How much can you eat before your stomach bursts? Can constipation kill you? Did it kill Elvis? In Gulp we meet scientists who tackle the questions no one else thinks of—or has the courage to ask. We go on location to a pet-food taste-test lab, a fecal transplant, and into a live stomach to observe the fate of a meal. With Roach at our side, we travel the world, meeting murderers and mad scientists, Eskimos and exorcists (who have occasionally administered holy water rectally), rabbis and terrorists—who, it turns out, for practical reasons do not conceal bombs in their digestive tracts. Like all of Roach’s books, Gulp is as much about human beings as it is about human bodies.
